1 Introduction
The purpose of this paper is to link to the results for the statistics obtained for the
IPC. The content of these statistics is precisely defined in the document “IPC_statisticsspecification_V2.0”.
The statistics have been obtained from the validity file querying it through an Access
database. The results are presented in an Excel worksheet linked directly to the Access
query, so when the result of the query changes, the worksheet is updated automatically.
